Hartwick College, Oneonta, N.Y., hired Boston Partners as a $9.9 million midcap value U.S. equity manager; Silchester International Investors as a $6.5 million international equity manager with a growth emphasis; and Harbor Capital Advisors as a $2.6 million international equity manager with a value emphasis for its $77 million endowment, said Susan Stetson, business manager. Boston Partners replaces Clover Capital Management, which previously ran $9.3 million; Silchester International replaces Warburg Pincus Asset Management, which previously ran $6 million; and Harbor Capital was hired for diversification. Funding came from rebalancing. Both replacements were due to unsatisfactory performance, Ms. Stetson said. Michael Jones, managing director for Clover Capital, said, "We met their needs for five years, but unfortunately we werent able to keep up with what they wanted this year. Brady Lipp, managing director for Warburg Pincus, was unavailable for comment.
